l. it known theivve, JOSHUA li. MAnviL or ii ein" ,fio Bowne, citizens ci the United iliza'ies, residing et Laurel, in the county oii Sussex and Stute oi lelawiire, have invenied neuv and useful improv-e niente iu Blow-Ouieicliee, of which ihe 'following a specification.

Our present invention relates io improve menis in repair patches for 'pneumatic fires, and the primary object is to provide animexpeneivo (ieiee oi" thie oharecier `which is capable of being easily nucl quickly epplieii and Ywhich will protect ihe inner tube from blowingv out through the outer casing or ironi being` injured by Contactl with zi broken or weakened portion yoi" the raising, .the patch., according' to the present' invention, being eubeientially in ihe i'orm of :i handage which is Wrapped around the ru-he, ii lacing So eh: pecl that it avoids the formation oi' an abrupt Shoulder which would i'eiul io chai'e und injure the uhe, and ii; has an adhesive eo applied as to preventcreeping or displacement oi ihe patch as Well ne io reuin the eouvoluiions thereof in proper posiiion.

To ihese and other eufis, the invention consists in cfm-'hihi firmemente and com binaiions eno errungemenie oi parte, :ill es will 'he hereiuaiiier more full] describech the novel 'features being` pointed out particularly in the claims el; the end/of 'the Specification'.4

Repair patches embodying' the present in venii'm are cupahle oi use in connection with a pneumatic `tire of any foniiiifusing on inner inflatable tube. in Tige. 12 1' 5l and (i ihree fiiii'ereni; forme oi" porches aiiei ehovm.y in Fig. LLilie paieh emholiesh haml 1 com: posed of inelastic ficiihie materiel such Aifor example ascanvas, or can 'ne mui i'ul':-hei.` The hand tapers from one end toward ihe i'iiliei-iimt ie "to airy, iis lougiiiuliual,eiioee converge ifo order that When the ihiclier .cnil of the bend is applied io the iihe and the i'hinner end ie Wrapped about the ruhe in convoluiiions, 'the patch will have ite` greet est ufiiiih next to the iuhe and 'will diminish in "ividih out 'ar(lly, orerlappiug` of .'ihe edges oi" i'he patch heilig i'herehy ai'oileei and the ends 'of the patch will. he l'ieieleil or will. slope from its ouiermoet to iis inner-- moet convoluiioii.

minishiiig .in width as it proceeds from the body section 4. The patch in this instance is preferably composed of a flexible inelastic fabric such as canvas or canvas and rubber,

and one side of the fabric has an adhesive such for example as rubber cement. In applying a patch of this type,

the Widened'body section 4 is fitted to thetube in aposition where it will cover the weakened or broken portion of the casing,

l the adhesive side of the bandbeing outerf face of the patch will be .presented to thek 'volutions and retain them in place.` Also,

`fwhen the tube having the patch applied thereto is placed in the casing and the tube is inflated, the adhesive on lthe outer surwall of the casing and will become firmly united thereto, thereby preventing creeping 1 or movement of the lpatch within the tire. In Figs'. 3 and 7 7 designates the outer casing, Sutlie inner tube, and 9 tlie Wheel rim to lWhich the tire is applied. v

What is claimed is 1. A repair patch for pneumatic tires r. .comprising a bloWout covering section, a flap extei'iding from one side thereof, and a band extending from the opposite side thereof and diminishing in Width in adirec tion from said section toward its free end.

2. A repair patch for pneumatic tires comprising a blow-out covering section, a

flap extending from one side thereof, a banda extending from the opposite side thereof, and an adhesive applied to one side of said section and band. ii;

3. A repair patch for pneumatic tires comprising a blow-out covering section, a flexible band extending` therefrom, one side of said section and baiidbeing adhesive, and a flap smaller iiidimensions than said section and extending from an edge of said section and fold'able upon the adhesive side tliereof.-
